. My-invention relates to improvements in 13 in such manner that thelongitudinal axis flying machines and the objects of my imof the motorsmay be adjusted to assume provement are to provide a fling machineeither a vertical or horizontal position. suitable for landin upon lanor water. When the motors are adjusted to a vertical 1 s, It isa'iurther o ject of my invention to position they will cause the craftto rise verto provide a hydrogen tank serving the double tically, andwhen adjusted to a horizontal purpose of acting as a reservoir for gastoposition, the motors will draw the craft ion till inflatable bags and asa. pontoon f01'l2nd-' wardly. The motor t is" likewise mounted ing inwater; an to also provide wheels between uprights 12 and is adjustablefrom to for landing upon the g'ound. a vertical to a horizontalposition. to it is a still further o ject of the invention In order toadjust the meters 8 and 9 from to utilize the inflatable bags to.efiectlanda vertical to a horizontal position, or vice ing of the craitby utilization of ated gas versa, the motors 8 and 9 include a shaft 14:begs in conjunction with the power units having a crank 15. -One end ofa link 16 is of the craft. v attached to the crank, the opposite endoithe dd Additional objects, i vantages and fealink being connected to ahand lever 17.
